- 

<script type="text/javascript"> function random_playlist(){     var myrandom=math.round(math.random()*4);     var soundurl='http://dummy.xy/dummy.mp3';      if      (myrandom==0){soundurl='http://path_to.mp3';}     else if (myrandom==1){soundurl='http://path_to.mp3';}     else if (myrandom==2){soundurl='http://path_to.mp3';}     else if (myrandom==3){soundurl='http://path_to.mp3';}     else if (myrandom==4){soundurl='http://path_to.mp3';}     console.log(soundurl);     return soundurl;     }; </script>  <audio id="audioplayer_id" controls="controls" loop> <source id="source_id" src="" type="audio/mp3"/> browser not support audio element </audio>  <script type="text/javascript">     var audioload = random_playlist();     console.log(audioload);     document.getelementbyid('source_id').src= audioload;     var audioplayer_id = document.getelementbyid('audioplayer_id')       audioplayer_id.volume = 0.15;       audioplayer_id.load();        audioplayer_id.play(); </script>

works me can optimized or ok ?

i hacked various sources seems html5 didnt integrate playlist function in audio tag, seems funny me. greets

you shorted random_playlist function this:

function random_playlist(){     var paths = ['http://path_to.mp3', 'http://path_to.mp3', 'http://path_to.mp3'];     return paths[math.floor(math.random() * paths.length)]; }

or (a better more complicated version):

var random_playlist = (function(){         var paths = ['http://path_to.mp3', 'http://path_to.mp3', 'http://path_to.mp3'];         return function(){                 return paths[math.floor(math.random() * paths.length)]         }; }())
